What is an injection moulding machine?

A look at the plastic injection moulding machine and its process

Since the patenting of the first injection moulding machine in 1872, the injection moulding process has come a long way.

We have long moved on from producing only small products such as buttons and hair combs, to now including every imaginable industry including medical, automotive, and aerospace.

What is an injection moulding machine?

A plastic injection moulding machine, also called an injection press, is a piece of production equipment that is used to produce plastic items via a moulding process.

The typical setup of a moulding machine consists of a hopper, an auger or screw conveyor with heating and temperature control elements, and the mould tool.

The mould tool can be further divided into the sprue, the runner, the gate and the cavity.

Let’s take a look at the uses of these parts and the moulding process.

Injection moulding

What is the injection moulding process?

Injection moulding process consists of six, easy to follow steps that result in your finished product:

• Clamping
• Injection
• Dwelling
• Cooling
• Opening
• Ejection

1.      Clamping

The mould has to be clamped shut to contain the pressure of the molten plastic as well as to seal any coolant channels that may pass through sections of the mould.

2.      Injection

The injection moulding process begins at the hopper. The granules or resin are fed into the hopper which directs them into the auger. The auger, which is heated to a controlled temperature, pressurises the plastic as it is being melted and forces it into the mould tool.

Some machines may carry a ramming tool instead of an auger.

The molten plastic enters the mould tool via the sprue, which is a nozzle from the auger that is fit snug against the opening of the moulding tool. The molten plastic then travels through the runner which is simply a passageway that guides the molten plastic.

The molten plastic then reaches a narrowing, known as the gate and from here is injected into the cavity. The cavity is the moulding of the finished product being manufactured.

3.      Dwelling

Dwelling is the process of increasing the pressure of the molten plastic in the cavity to ensure that all the areas are totally and uniformly filled.

4.      Cooling

The plastic in the cavity is then cooled for it to harden. Moulds can be air-cooled but it is much more efficient and effective to utilise a coolant such as water to control the rate of cooling of the finished product.

5.      Opening

After the part has solidified, the clamps are opened to reveal the finished product.

6.      Ejection

This is the removal of the finished product from the mould. This can be done manually or automatically such as with an air blast system.

Some mould tools carry multiple cavities for the production of multiple parts from a single injection. These usually carry cold slug wells at the turning points of the runners. These cold slug wells capture the colder molten plastic to reduce the risk of inconsistencies in the finished product.

Improve Your Bathroom Hygiene Factor with Hands-Free Solutions

Why Use Hands-Free Technology?

Multi Knee Operated Trough

Cut Back on Water Costs

Are your company expenses high? Hands-free technology allows businesses to significantly save on water bills. A business with normal faucets has to worry more about employees wasting water. Due to the way that the water is turned off manually, there is a possibility that a worker will leave the water on unintentionally. Whether the faucet is releasing full streams of water or just small water drips, this water leakage is costing your business money. Hands-free technology is an easy solution to prevent unnecessary water usage. Using sensors causes your water to turn off automatically when no one is using the faucet.

Cut Back on Energy and Supply Costs

A business can also expect to save on energy if it switches to hands-free technology. Hands-free hand dryers turn on and off using sensors. If a person is not nearby, the sensor will not activate the hand dryer. The hand dryer will also turn off automatically so that it is not left on accidentally. Employees drying their hands with hot air instead of paper towels also helps a company save on supply costs over time.

There is usually a 95% cost savings with using hand dryers versus buying paper towels. To help companies save money, Britex offers seven hands-free automatic hand dryers for purchase. The hand dryers use sensors to detect when hands are presented and when they are not. This allows the device to operate only when you want it to, which helps save on energy costs.

Improve Hygiene Among Your Workforce

A sick worker means that your productivity goes down temporarily in the work place. Many work places encourage their workers to come into work sick. However, one sick worker can infect an entire work force. By installing hands-free technology in your company’s restrooms, you can cut back on the spread of the disease. Germs like to stick to hard surfaces and they can transfer from one individual to another. A sick individual may touch a faucet handle and end up spreading their sickness to the next individual that touches the handle. By limiting how many items that employees have to touch directly with their hands in the restroom, you can limit cross contamination of germs.

https://www.britex.com.au/knee-operated-hand-basin

Automatic soap dispensers are a great option for hands-free bathrooms. They use a sensor to tell the device when soap should be released. Britex offers the Automatic Stainless-Steel Soap Dispenser for purchase. The device uses infrared sensors so that employees never have to touch the device in order to request soap. The device also only releases one drop of soap at a time in order to limit how much soap an individual can ask for. This allows companies to save on soap over time.

Britex also offers hands-free water basins and water troughs. Some of their basins come with a wand instead of a regular handle. At first, you might assume that you need to toggle the wand with your hands in order to turn on the water. However, you can actually lean against the wand to activate the basin so the product is completely hands-free. Britex also offers troughs and basins that are knee-operated, which is another creative way to get around having to use your hands. Sensor activated troughs are also available as a hands-free alternative to regular troughs.

Upgrade Your Company Bathrooms

Technology is changing. New inventions are made with the purpose to make our lives easier and safer. Hands-free technology is just one of these inventions. By using hands-free technology, you can guarantee that you are helping your work force be more hygienic and less wasteful. This means that your company will experience less interruptions in productivity due to sick workers and profit more in the long run.

Industrial and Commercial Scales: What You Need to Know

There is a wide range of uses for scales, and there are many different kinds. We use scales to cook, weigh ourselves, and to weigh products. But, with such a wide selection of scales, how are we supposed to know which ones to buy?

In this article, we’re going to cover the differences between industrial and commercial scales. Then you will have a better idea of which scale you’ll need for your specific purpose.

industrial scale

What are industrial scales?

Industrial scales are designed to withstand harsh industrial environments. These scales are adaptable, affordable, and durable. They last a long time and are reliable.

 

Suppliers that have industrial scales will weight out products, package, and label them in advance. You can house these scales inside your shops and use them whenever you’d like. These scales don’t have to meet “legal for trade” requirements, and they’re usually not NTEP certified. They are still precise and provide accurate data.

 

These scales tend to be larger than commercial scales. They aren’t ideal for commercial businesses like candy stores. Industrial scales are essential for catching precise measurements, which is perfect for industrial businesses.

commercial scale

What are commercial scales?

Commercial scales tend to be smaller and are ideal for commercial businesses. Suppliers will use these scales in front of the customer to show them the weight. The supplier will then package and label the product. For instance, think of candy shops or the meat market.

Unlike industrial scales, the National Bureau of Standards regulates commercial scales. The bureau sets the standards for the scales’ operation, accuracy, and label printing. The bureau is also in charge of determining how users must enter the price per kilo or per pound.

These scales are ideal for smaller shops like delis, candy stores, cheese shops, and bakeries. Independent shops and small businesses rely on commercial scales to run their day-to-day operations.

industrial and commercial scale

The difference between commercial and industrial scales

Now that we’ve gone over the difference between commercial and industrial scales, let’s figure out which one is best for you. Here are the main factors you should pay attention to when buying a scale:

  • Size: If you own a smaller shop, you are more likely to go with a commercial scale. These scales are ideal for smaller locations, while industrial scales are made for larger businesses.
  • Certified: Want your scale to be NTEP certified? Then go with commercial scales. These scales have gone through processes set by the bureau to ensure functionality. But this doesn’t mean that industrial scales aren’t accurate. They can actually be more accurate than commercial scales.
  • Packaging: If your shop requires you to package your product in front of customers, then you need a commercial scale. If you can weigh your products, package, and label them without customer approval, then you can use an industrial scale.

Knowing the difference between commercial and industrial scales is important. Choosing the right scale for your business is essential to running your day-to-day operations. Check out industrial and commercial scales to find the right fit for your company!

How to keep Your School Science Lab Safe

When it comes to science, hands-on learning is considered essential to the comprehension of the subject matter. Seeing the effect of their experiments in action tends to result in a firmer understanding of what brought upon the result. That’s why a science lab can be found in most middle school, high school, and college science classrooms.

Even though this hands-on learning style in lab classrooms is an essential tool for students, these rooms are also places where students can be placed in dangerous situations. Discover Magazine found that accidents in schools and colleges are 100 to 1000 times as frequent as those occurring at major chemical companies.

Using proper methods to keep labs and the students within them safe is therefore paramount. The following safety tips can help keep everyone in a lab as safe as possible

lab equipment

Clear Communication

The best way to prevent lab accidents is to lay out a clear explanation of the experiment that will be performed and a printed version of specific guidelines and instructions should be provided to the students. It is essential to explain the experiment before entering the lab. After students enter, they may be too distracted by the supplies and tools to hear the experiment instructions, cautions, and warnings. They may also want to get a jump start on the work. Students should be encouraged to read the printed steps for the experiment ahead of time, more than once if necessary for a firm understanding. By explaining everything before the work starts, the distractions can be mitigated.

Students may have questions before the start of the experiment and it is essential to make sure that all of those questions get addressed. These questions may not be exactly relevant but it is always good that they are asked and answered before starting as they may touch upon safety topics that need to be restarted or clarified.

Students should be encouraged to ask their questions if they are not sure of certain details as it pertains to the experiment’s ingredients, or the experiment itself. Doing so could clear up any misunderstandings that can lead to accidents.

laboratory equipment

Safety Measures

One of the key components of lab safety is taking every precaution necessary. This includes wearing lab appropriate gear. When dealing with heat or dangerous chemicals, it is vital to wear protective clothing. These pieces should be provided to the students, should be put on as soon as they enter the lab, and no activity should start until everyone has confirmed they have what they need.

The gear required for a lab may vary depending on the experiment. Lab coats are almost always a must as many things can damage or ruin clothes. For certain experiments, lab aprons are called for. When dealing with heat or chemicals, gloves are also essential to protect the students’ skin.

Eye protection is vital. Aside from being tempted to touch them with hands which may have harmful particles on them, the eyes are sensitive enough to be affected by splashes, burns, and even vapors from certain experiment components.

Long hair should always be pulled back into a ponytail before an experiment begins to protect it from getting caught in equipment, burning, or being exposed to chemicals. Any loose clothing, like scarves, should also be removed before starting.

Ensure Quality Equipment

The equipment used in lab classrooms may be expensive, but it’s far less costly than a malfunction that could bring harm to a student, instructor, or the school. It is always worth investing in high quality laboratory equipment that are durable and that meet the required standards, rather than opting for cheaper alternatives.

If a piece of equipment is malfunctioning, it should be thoroughly repaired if possible. If a complete repair cannot be performed, it should be disposed of and replaced.

All water sources, including eyewash stations and showers, should be confirmed to be functional. All exhaust hoods should be verified as working. Fire extinguishers and fire blankets should be present. A bucket with 90% sand and 10% vermiculite (properly labeled) should be securely tightened, but available.

Heat safety equipment like gloves, mittens, and tongs should be available and required during the use of experiments dealing with handling cold and hot objects.

Lab Maintenance

After the experiments have completed, it is important to have all of the equipment put away and for all used work surfaces to be wiped, which should remove any corrosive materials and help prevent injury from those using it next.

All equipment should be fully turned off and debris should be properly disposed of. Burners, warmers, any other equipment that requires being turned on should be disposed of. Any items that remain operational, especially when no one is around, could cause serious and irreparable harm to the lab and the school building.

5 benefits of using a checkweigher

Many different types of companies, spanning multiple industries, use a checkweigher scale for a variety of uses. The checkweigher is different from using a basic scale because it has programmed in sensory tolerance. Through a series of colored lights and digital readouts, the checkweigher can provide exact weight numbers, allowing one to easily determine if the weight is under, over, or on target with the needed or desired product weight.

There are more benefits of using a checkweigher than just their precision, and it has to do with the ramifications of being able to obtain this exact weight, and what that could mean for the company using it. The following are some of those benefits.

Checkweigher

Ensures Product And Packaging Quality

During the quality control process of most products, whether it is automotive or consumable goods, accurate weight measurement is a key component requiring a precise weight reading. An accurate weight reading can help recognize problems that would cost the company money and have them be mitigated.

As an example, a baked item that weighs too much may end up being undercooked, whereas one that weighs too little could be overcooked. The checkweigher helps ensure that the exact weight of the dough used in baking is utilized to result in optimal production. If the company’s baked goods are persistently over or undercooked, consumers will opt for another brand that does not have these issues, costing that baking producer lots of business and hurting their bottom line.

checkweigher scale

Increased Accuracy, Reduced Giveaway

One of the top benefits of checkweigher use is the financial savings it provides. Many products have their weight correlated to cost savings. A lot of times, the accuracy of weight can mean the difference in whether the producer is profitable or not.

Take for instance the distribution of strawberries, which are typically packed inside of a plastic container. Say the container is meant to weigh 2 pounds (including the container itself). If 10 containers are packed to weigh 2.1 pounds instead, the producer would have given away half the cost of one container. A checkweigher allows for a more accurate packing amount, assuring that the container retains exactly 2 pounds of strawberries. For many companies, this seemingly nominal savings can yield tens or hundreds of thousands in extra profit annually.

Meets Regulatory Compliances

Many products are produced in containers that specify the exact weight as specified by regulatory guidelines. If the weight labeled is not equivalent to the weight actually in the container, in certain industries company’s could be subject to heavy fines by regulatory bodies due to failure to meet compliance standards.

Every region has its own regulatory rules, and the fines can vary based on geography. Considering that some can be more substantial than others, multiple regions levying fines against a particular company could have devastating financial consequences by resulting in a massive loss of revenue. These could mean the difference between a company staying in business and closing its doors.

checkweighers

More Efficiency In Production

Utilizing a checkweigher will allow for more accurate data to be provided, allowing management to access production quality. They may find that the process is inefficient in certain areas and take that data to help tweak the process for better efficacy. There might be certain parts of the process that can be better utilized or improved to speed up production or more accurately put the final product together.

If there is inconsistency in weight, it may mean that certain equipment is not working properly and may need recalibration. That will allow the necessary steps to be taken to get production up to its optimal state.

Tracking Labor Productivity

This can also be used to track the productivity of the labor force. A checkweigher can save on operational labor by providing management with the data about who measured weight using the scale, when they started, finished, and how long it took them to do so. This is important data that could provide time trial samplings and allow for adjustments to be made or labor being restructured to improve to a more cost-effective, optimal output.

It’s one thing to have an advanced CNC Plasma cutter with all the latest features but it is another thing to be able to make use of all these capabilities. Do some research about the software of the product before you purchase it. Make sure it is user friendly and doesn’t need a rocket scientist to figure it out.

You may also choose to purchase additional features for your machine such as a water pool bed or extraction systems. These also improve the operator’s comfort and reduces the contamination of your workpiece and workspace.

Operational Cost

cnc plasma cutter

This is where most persons make a huge blunder when budgeting for new equipment. The purchasing cost of the machine is a one time cost but it is actually the least important cost. The one to watch is the operational cost of the equipment. You will have to pay each time you use the machine and I am not only referring to your operator’s salary.

There will be electricity usage to power the cutter, motors,  computers, and other additions such as extraction fans.

Ensure that you properly determine everything that you want your new CNC plasma cutter to do for you as well as your operating budget. Then, do your research and talk to your supplier to find the best equipment that will match all your requirements. This ensures that purchasing the machine results in a benefit to your operations.
